Arctica - Complete Remastered Discography [MP3-256] [cxcr6-006]
Completely improvised tracks using all sorts of various instruments, with a microphone hanging somewhere in the room (usually a lightbulb). Recorded on various things including dictaphones, camcorders, 4-tracks and laptops.
This is sometimes beautiful, sometimes horrid. But always extremely experimental. This is post-rock taken to its limits.
7 - Improv number 1 (live)
